Dispersing carbon nanotubes in phenolic resin using an aqueous solution
(2011-11-01)
The ability to control the carbon nanotube (CNT) dispersion in polymers is considered the key to most applications of nanotube/polymer composites. The carbon nanotube dispersion into water with different surfactants, as ...
Effects of amine molecular structure on carbon nanotubes functionalization
(American Scientific Publishers, 2009-10)
Three amines with different molecular structure, triethylenetetramine (TETA) and two polyetheramines (Jeffamine D-230 and Jeffamine T-403) were employed to functionalize multi-walled carbon nanotubes (MWCNT) previously ...
Adsorptive stripping voltammetric determination of nitroimidazole derivative on multiwalled carbon nanotube modified electrodes: Influence of size and functionalization of nanotubes
(2011)
1-Methyl-4-nitro-2-brominemethylimidazole (4-NimMeBr), was electrochemically reduced on mercury, glassy carbon and multiwalled carbon nanotubes (MWCNT) modified electrodes. 4-NimMeBr was adsorbed on the MWCNT modified ...
On the Energetics of Ions in Carbon and Gold Nanotubes
(Wiley VCH Verlag, 2016-01)
We investigate the insertion of halide and alkali atoms into narrow single-walled carbon nanotubes with diameters <9 Å by density functional theory; both chiral and non-chiral tubes are considered. The atoms are stored in ...
Viscoelastic Behavior of Multiwalled Carbon Nanotubes into Phenolic Resin
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2013-07-01)
Nanostructured polymer composites have opened up new perspectives for multi-functional materials. In particular, carbon nanotubes (CNTs) have the potential applications in order to improve mechanical and electrical performance ...
Effect of Nanotube Functionalization on the Properties of Single-Walled Carbon Nanotube/Polyurethane Composites
(John Wiley & Sons Inc, 2007-12)
A commercially available aliphatic thermoplastic polyurethane formulated with a methylene bis(cyclohexyl) diisocyanate hard segment and a poly(tetramethylene oxide) soft segment and chain-extended with 1,4-butanediol was ...
Thermal treatment of the carbon nanotubes and their functionalization with styrene
(Elsevier Science, 2009-07)
In this work we studied the functionalization of commercially available multiwalled carbon nanotubes (MWCNT) (Nanocyl 3100) with polystyrene by the method so called "grafting from". The nanotubes were used as received and ...
Improving carbon nanotube/polymer interactions in nanocomposites
(Elsevier, 2017)
A review of carbon nanotube (CNT) functionalization methods to improve the interfacial interactions with polymers is addressed. The most common CNT functionalization methods to address the issue of interfacial interactions ...
Structural, electronic and magnetic properties of vacancies in single-walled carbon nanotubes
(ELSEVIER, 2006-09-15)
The monovacancy and the divacancy in single-walled carbon nanotubes (CNTs) are addressed by spin-density functional calculations. We study these defects in four nanotubes, the armchair (6,6) and (8,8) and the zigzag (10, ...
